MODE OF CONSTRUCTING A COMBINED STREETJLAVEMENT AND RAILROAD-TRACK.

Specification of Letters Patent No. 22,665, dated January 18, 1859.

To all whom it may concern:

Be it known that I, Rienixno MoNr- (renner, ofthe city and county ot New X ork,

in the State of New York, have invented a t new and uset'ul Improvement in Combined Street-Pavements and Railroad Tracks; and l do hereby declare that the following is a full description thereot.

To enable others skilled in the art to which my iinprovenient belongs to construct and use my improvement, I will now proceed to describe the same, reference being had to the annexed drawings and to the letters of re't'erence marked thereon, forming a part ot' this specification.

Figure 1, represents a perspective View ot one ot' the arches ot' my combined street` pavement and rail road track; Fig. Z, is a similar view, the only dilterence between Figs. 1, and 2, being that in Fig. i), the arch is represented to span the whole width ot' the street from curbstone to eurbstone, while in Fig. 1, the arch covers only part of the width of the street between the` cnrbstones; Fig. 3, exhibits a section across one of the arches, on a large scale; Fig. l, is a perspective and Fig. 5, an end View representing moditifations of the arrangement ot' the track as shown in Figs. 1, L), and 3.

A, B, C, D, represent one of the arches which when put together constitutes a continuous street payement and rail road track. These arches consist of parallel corrugations o, a, a, which are intersected by two or more rail tracks b, the rails and corrugations being cast in one piece. The bottom part of the arches is provided with projections d, (l, at suitable distances from each other, for the purpose ot' strengthening the central portion ot' the arches between the rails b, l).

Figs. 1, and Q, represent hollow rails, suitable for city railroads; Fig. 5, represents a dovetailed rail suitable for the insertion ot' a raised rail c, as shown in Fig'. Jr.

f', j', are the eurbstones and c, c, in Fig. 1, represents the street payement in coniinon use.

The foundation of the arches is formed ot' concrete g, g. The spaces between the corrugations may also be filled with concrete as seen at r, Il., Fig. 3.

The projections f1, (I, instead of extending across the track as seen in Figs. 1, 2, and 3, may be arranged in line with the rails l), l), as represented in Fig. 4. The arches how ever can be laid ou common light soil with out the use ot any concrete.

(.)ne great objection to the introduction of rail roads into citiesand large towns arises from the ditliculty and expense of keeping them in proper repair. ln all cases where the street has to he repaved or where the payement needs repairs, it cannot he done without disturbing the track. Neither can the track be repaired without disturbing to a greater or less degree, the street pavement. Again, in most cases, the rails are continually liable to be displaced hv the settling' or displacement of one or more stones or blocks oli the street pavement. By adopt ing my plan of a combined street pavement and rail road track, all or nearlv all o'lE these objections are obviatcd. That this is thtI case, will be apparent when it is remembered that my pavement and track are cast together. So 'tar as the pa vement is concerned. it resembles my improved street pavement. t'or which l have applied tor Letters Patent. It is formed of parallel arched corrugatious. said corrngations beingl cast thicker on the top than on the bottom as seen at o, n, Fig. Il. These corrugations may extend on either side of the grooved track I), o, to the curbstones f, as represented in Fig. In laying this track however` in streets which are now paved, it may be best` perhaps, to let it extend but a short distance on either side ot' the track (as seen in Fig. 1,) as by this mode ot' construction a good tootway will be ohtained in the center of the street tor horses, while at the same time a sutlicien amount ot surface. of the pavement will come in contact with the ground to render the pressure on any one point` under the liaiyiest loads, but trilling, when compared to what it would be. it the track and parement were separate.

In laying my combined pavement and rail road track. no sleepers are required. and the sections are laid at once n.pon the prepared ground or roadway, the projections rl, (l, answering the purpose of sleepers. As no sleepers are used, there is none to be repaired, consequently, when a track at'tcr my plan is once laid, it will last for years: with but little liability to get out ot order.

In most cases it will be found unnecessary to add or use wrought iron rails, the flanges of the wheels running in the grooves l), o, cast for that purpose on the upper face ot the pavement. It' howeyer it should be deltl siiiml. \\'|on;l|t mils nmy lm i'nn into the gi'oovw (':Lnt on tln` nppli' liznfi oll tho pztvt nnnt, :in i'tplt'st-ntlrtl in Fig'.
